I don't know where it came from, but there is a box full of what appear to be Firefox control icons over to the right of my Google search field on the toolbar. There are two rows; on the top row, they are all greyed-out, if looks like 'back', 'forward', 'reload page', 'cancel', 'downloads', and so on (they're icons, not words, but I think that's what they correspond to). On the bottom row, there's one like a clock, and one like 'favorites', those are in white. Clicking on any of this stuff does nothing, and if I double-click and hit 'customize', the whole box behaves as a single object, but I can't delete it.

I'd be happy to add a screen shot, but I don't know how. I looked around the Mozilla pages and the internet, but I don't see anything like this. Sorry! Thanks!
